Cell Phone Tracking
What would life be like if we could know where someone is at all times? With cell phone GPS, we can find out. The recent growth in the popularity of cell phone GPS has brought into existence the ability to not only obtain directions to any desired place, but also track someone via their cell phone. Cell phone GPS, although many think that it takes away their right to privacy, has helped, and continues to help, us navigate our way through this world.
So, how does it work? GPS works by sending out signals that are picked up by GPS receivers. The Global Positioning Satellite (GPS) analyzes the signal and relays the information on to the user. Although originally designed for government use, the ability of GPS to determine the position, speed, and direction of a cell phone has brought the popularity of cell phone GPS into the lives of ordinary citizens.
GPS track cell phones better than triangulation that was used before GPS technology. Triangulation determines which three cell phone towers to which phone is the closest. That is how they determine the approximate location of the cell phone. Although it isn't as precise, sometimes as much as tens of meters off, it did give a pretty good indication of location. The Cell Phone GPS, on the other hand, can pinpoint the location of the cell phone within about five meters. That makes the GPS roughly ten times more accurate than triangulation.
The use of cell phone GPS have helped to save lives and continue to help. Since the cell phone GPS is nearly pinpoint accurate, it can help with both emergency 911 calls as well as missing person situations. For instance, if a person is missing, and his or her cell phone is left on, the phone can be traced using the GPS. This is an amazing advantage to the investigation. Today, most cell phones have GPS capabilities so when someone calls 911, the phone sends the GPS information to the 911 operator.
Cell phone GPS has proven itself to be very helpful in emergency situations. However, it has also made its way into the lives of ordinary citizens, in the form of navigation systems. Many modern cars have GPS systems in them. In the last few years, cell phone service providers have developed applications of this same type. These applications, such as Verizon Wireless' VZ Navigator, give the user step-by-step direction to any desired place. Many of them even offer voice commands, like "Turn left at the next intersection."
GPS in cell phones has seen major growth over the past few years. Its extremely helpful and convenient features have brought GPS from the government into the everyday lives of ordinary people. This change in scenery has aided in the greatly increasing popularity of GPS. Because of this popularity, GPS will, very likely, continue to see growth in its features and usability in the near future.
